In life, we often need to take the elevator, but you know, although many elevators are made by us, the machine tools that produce elevators are imported from abroad. One of the difficulty is that the press brake machine needs to be used in the production of elevators. Currently, the domestic equipment can only do the unilateral bending, which requires manual assistance when encountering the multilateral bending. Many people do not think that we often take the elevator in our lives, and many of the machine tools are imported. Take the elevator door as an example, the elevator door we see seems to be a plane, but actually, it's a "square box". The outside of the elevator has a door panel, and there is a door panel inside, which is hollowed-out in the middle.The elevator doors need to be folded into a "square box". It's like taking a piece of paper and folding it into a box.  Among them, folding this "square box" needs to use bending machin...

The upper roll of the rolling machine is in the central symmetrical position of the two lower roll. It acts vertically on the piston through the hydraulic oil in the hydraulic cylinder, and drives the two lower roll gears to move together and rotate through the last gear of the main reducer, so as to provide torque for the rolled sheet. The leveling plastic plate is made up of three roll bending machine, with the help of the upper roller's lower pressure and the rotation movement of the lower roll, so that the metal plate can be continuously bent through multiple passes. A permanent plastic deformation is produced to be rolled into the required cylinder, cone, or part of them. The drawback of the three roll bending machine is that the end of the plate must be prebent with the aid of other equipment. The rolling machine is suitable for large rolling plate machine with the thickness of 50 mm.  Safety operation procedures for  three roll bending machine cnc rolling machine ...

For a client buying sheet metal fabrication machinery, most worrying thing is how to guarantee the safe transportation and save the cost of it. Today let talk about this theme. Different with consumer goods, the machine has a large size and weight, like big size press brake and shearing machine, also with complex and precise structure. Suitable container and stable fixing is the key point. Widely used in machinery industry is 20' /40' GQ (general container), 40HQ (high container), 20' /40' OT(open top container). If the machine is much larger, flat rack container is the leading part. 20' GQ is a good choice for a small machine, like power press, ironworker and some duct forming machine. When the height is over 2100mm, need to level up to 40' HQ container. Some machine like pneumatic power press, as its height, need to be laid down in the container. But if the machine is too heavy and large, it's necessary to separate and use several containers. Such as...
